Abstract
Description
本発明は、回転刃切削装置及び軽量気泡コンクリートパネルの切削加工方法に関する。 The present invention relates to a rotary blade cutting apparatus and a lightweight foam concrete panel cutting method.
軽量気泡コンクリート（ＡＬＣ）パネルは、耐火性、断熱性、施工性に優れているため、建築材料として広く使用されている。 Lightweight cellular concrete (ALC) panels are widely used as building materials because they are excellent in fire resistance, heat insulation and workability.
ＡＬＣパネルは、珪石等の珪酸質原料と、セメントや生石灰等の石灰質原料とを、主原料とし、これらの微粉末に、水、石こう、アルミニウム粉末等の副原料を加えたスラリー状のＡＬＣ原材料を、予め補強用鉄筋が並べられた型枠に鋳込んで硬化させるプロセスによって製造される。型枠に鋳込まれたＡＬＣ原材料は、アルミニウム粉末の反応により発泡し、石灰質原料の反応により硬化が進行する。そして、半硬化状態のＡＬＣを、ピアノ線によりパネル状に切断した後、高温高圧水蒸気養生によって硬化を完了させることによりＡＬＣパネルが完成する。 The ALC panel is a slurry-like ALC raw material that consists mainly of siliceous raw materials such as silica and calcareous raw materials such as cement and quicklime, and auxiliary materials such as water, gypsum and aluminum powder added to these fine powders. Is manufactured by a process of casting and hardening into a formwork in which reinforcing bars are arranged in advance. The ALC raw material cast in the mold is foamed by the reaction of the aluminum powder, and hardening proceeds by the reaction of the calcareous raw material. And after cut | disconnecting ALC of a semi-hardened state in a panel form with a piano wire, an ALC panel is completed by completing hardening by high temperature high pressure steam curing.
ＡＬＣパネルは、上記の製造プロセスからなるものであることより、その内部に多量の気泡を含む。しかしながら、これらの気泡のうち、切断面近傍の気泡については、上述のように、半硬化の状態での切断時に押しつぶされて消失する。よって、ＡＬＣパネルの表面（ピアノ線による切断面）は、気泡の露出がほとんどなく、平滑な状態となる。 Since the ALC panel is composed of the above-described manufacturing process, it contains a large amount of bubbles inside. However, among these bubbles, the bubbles in the vicinity of the cut surface are crushed and lost during cutting in a semi-cured state as described above. Therefore, the surface of the ALC panel (cut surface by the piano wire) is in a smooth state with almost no bubble exposure.
一方で、例えば、ＡＬＣパネルの目地面に形成される面取り面等、ＡＬＣパネルの硬化後に切削加工によって形成される面については、上記の切断面（ピアノ線による切断面）とは異なり、切削加工後の表面が、直ちに平滑な状態とはならない。このような面取り面は、一般に、回転する切削用刃物を備える回転刃切削装置で切削加工されて形成されるが、切削加工後の切削加工面の表面には、ＡＬＣパネルの表面近傍に潜在していた多量の気泡が露出した状態となってしまうからである。 On the other hand, for example, a chamfered surface formed on the joint surface of the ALC panel, such as a chamfered surface, which is formed by cutting after the hardening of the ALC panel, is different from the above cut surface (cut surface by piano wire). The subsequent surface is not immediately smooth. Such a chamfered surface is generally formed by cutting with a rotary blade cutting device provided with a cutting tool that rotates. However, the surface of the cut surface after cutting has a potential near the surface of the ALC panel. This is because a large amount of air bubbles that have been exposed are exposed.
このようなＡＬＣパネル表面への気泡の露出は、ＡＬＣパネル外観の意匠性低下につながるため、これを回避するために、表面に露出してしまった気泡内への充填物の充填や、気泡が露出している範囲への塗料の塗布等、これらの気泡をパネル表面から消去するための追加作業が必要となる。ＡＬＣパネルの製造においては、この追加作業の煩雑さが、生産性を向上させる上での障害の一つとなっていた。 Such exposure of bubbles on the surface of the ALC panel leads to a decrease in the design of the appearance of the ALC panel. To avoid this, filling of bubbles in the bubbles exposed on the surface, Additional work for erasing these bubbles from the panel surface, such as application of paint to the exposed area, is required. In the manufacture of ALC panels, the complexity of this additional work has been one of the obstacles to improving productivity.
尚、通常、硬化後のＡＬＣパネルに対する上記のような切削加工を行う回転刃切削装置においては、良好な切削加工面と刃物の摩耗に対する寿命を確保するため、回転刃２の先端形状を、図２に例示するように、すくい角（θ１）がポジティブ（正の角度）であり、逃げ角（θ２）も３°以上の正の角度とすることが一般的であった（特許文献１参照）。 Normally, in the rotary blade cutting apparatus that performs the above-described cutting process on the cured ALC panel, the tip shape of the rotary blade 2 is shown in order to ensure a good cutting surface and the life against the wear of the blade. 2, the rake angle (θ 1 ) is generally positive (positive angle), and the clearance angle (θ 2 ) is also generally positive angle of 3 ° or more (Patent Document 1). reference).
尚、「すくい角」とは、回転刃切削装置の刃先において、回転刃の進行方向の前面に形成されている、すくい面の垂直面に対する角度のことを言う。図２に示すように、すくい面が垂直面に対して回転刃の進行方向とは反対側にある時のすくい角θ１を正のすくい角とする。又、これに対して、図３に示すように、すくい面が垂直面に対して回転刃の進行方向の側にある時のすくい角θ１を負のすくい角とする。 The “rake angle” refers to an angle of the rake face with respect to the vertical plane formed on the front surface in the moving direction of the rotary blade at the cutting edge of the rotary blade cutting apparatus. As shown in FIG. 2, the rake angle θ 1 when the rake face is on the opposite side of the vertical plane from the traveling direction of the rotary blade is defined as a positive rake angle. Also, whereas, as shown in FIG. 3, the rake angle theta 1 when the rake face on the side in the traveling direction of the rotary blade with respect to a vertical plane and a negative rake angle.
又、「逃げ角」とは、一般に工具が工作物と干渉しないようにつける角度であり、回転刃切削装置の回転刃においてはＡＬＣパネルの表面を削り取った後の刃先とＡＬＣパネル表面の不要な接触を避けるためのものである。通常、図２に示すように、０°よりも大きい角度θ２の逃げ角が設けられる。 In addition, the “relief angle” is an angle that is generally applied so that the tool does not interfere with the workpiece. In the rotary blade of the rotary blade cutting device, the blade edge after scraping the surface of the ALC panel and the unnecessary surface of the ALC panel surface are unnecessary. This is to avoid contact. Usually, as shown in FIG. 2, a clearance angle of an angle θ 2 larger than 0 ° is provided.
本発明は、上記状況に鑑みて考案されたものであり、ＡＬＣパネルの目地面に形成される面取り面等、ＡＬＣパネルの硬化後に切削加工によって形成される面の表面の平滑性を担保するための追加作業の負担を軽減し、ＡＬＣパネルの意匠性の維持と生産性の向上とを同時に実現することを目的とする。 The present invention has been devised in view of the above situation, and in order to ensure the smoothness of the surface of a surface formed by cutting after hardening of the ALC panel, such as a chamfered surface formed on the joint surface of the ALC panel. The purpose of this is to reduce the burden of the additional work and to simultaneously maintain the design of the ALC panel and improve the productivity.

以下、本発明の実施形態について説明する。但し、本発明は以下に説明する実施形態に限定されるものではない。 Hereinafter, embodiments of the present invention will be described. However, the present invention is not limited to the embodiments described below.
＜回転刃切削装置＞
本発明の回転刃切削装置１は、図１に示すように、モーター（図示せず）により回転する回転胴３に多数の回転刃２が設置されてなる切削装置である。主たる加工対象物としてＡＬＣパネル４が想定されている。
<Rotating blade cutting device>
As shown in FIG. 1, the rotary blade cutting device 1 of the present invention is a cutting device in which a large number of rotary blades 2 are installed on a rotary drum 3 that is rotated by a motor (not shown). An ALC panel 4 is assumed as a main object to be processed.
図３に示す通り、回転刃切削装置１の回転刃２は、その刃先２１のすくい角θ１が−５°以上０°未満であり、より好ましくは、−３°である。回転刃２の刃先２１のすくい角θ１が０度又は所定の負の角度であることにより、加工対象物であるＡＬＣパネル４の被切削面４１から削り取られた微細な切削屑のＡＬＣパネル４上方への噴出が抑制される。そして、切削の進行に伴い、これらの切削屑の多くの部分は、切削加工面４２Ａに流しこまれていく。 As shown in FIG. 3, the rotary blade 2 of the rotary blade cutting apparatus 1 has a rake angle θ 1 of the blade edge 21 of −5 ° or more and less than 0 °, more preferably −3 °. When the rake angle θ 1 of the cutting edge 21 of the rotary blade 2 is 0 degree or a predetermined negative angle, the ALC panel 4 of fine cutting scraps cut off from the cut surface 41 of the ALC panel 4 that is a workpiece. The upward jet is suppressed. And with progress of cutting, many parts of these cutting wastes are poured into the cutting surface 42A.
又、同じく図３に示す通り、回転刃切削装置１の回転刃２は、その刃先２１の逃げ角θ２が、−１°以上０．５°以下であり、より好ましくは、０°である。回転刃２の刃先の逃げ角θ２が、このように、０°又はその近傍の角度であることにより、上記の切削屑は、ＡＬＣパネル４の切削加工面４２Ａに押し付けられながら後方に流される、その際、これらの切削屑の一部である切削屑４４は、切削加工面４２Ａの表面に一時的に露出した気泡４３の内部に加圧されながら充填されていく。この作用により、切削加工面４２Ａは、切削直後の段階において一時的に露出していた気泡４３の存在にかかわらず、見かけ上平滑な状態となる。 Similarly, as shown in FIG. 3, the rotary blade 2 of the rotary blade cutting device 1 has a clearance angle θ 2 of the blade edge 21 of −1 ° or more and 0.5 ° or less, more preferably 0 °. . Relief angle theta 2 of the cutting edge of the rotary blade 2 is, in this way, by an angle of 0 ° or near, above swarf is flowed backward while being pressed against the cut surface 42A of the ALC panels 4 At that time, the cutting scraps 44 which are a part of these cutting scraps are filled while being pressurized inside the bubbles 43 which are temporarily exposed on the surface of the cutting surface 42A. By this action, the cut surface 42A is apparently smooth regardless of the presence of the bubbles 43 that are temporarily exposed immediately after cutting.
ここで、本発明の回転刃切削装置１は、図４に示すような形状の刃先２２を有するものであってもよい。この刃先２２は、同図に示す通り、回転方向前方部側の回転軸に対する垂直断面形状が半円形である。この場合、この半円の半径は２ｍｍ以上５ｍｍ以下であることが好ましい。又、この場合における刃先２２の逃げ角は、上記の刃先２１と同様、−１°以上０．５°以下であればよく、０°であることがより好ましい。この場合も、刃先の回転方向前方部側の形状が上記のような半円形状であることにより、加工対象物であるＡＬＣパネル４の被切削面４１から削り取られた微細な切削屑のＡＬＣパネル４上方への噴出が抑制される。よって、刃先２２を有する回転刃切削装置１も、刃先２１を有する上記の回転刃切削装置１と同様の作用効果を発揮することができる。 Here, the rotary blade cutting device 1 of the present invention may have a cutting edge 22 having a shape as shown in FIG. As shown in the figure, the cutting edge 22 has a semicircular vertical cross-sectional shape with respect to the rotation axis on the front side in the rotation direction. In this case, the radius of the semicircle is preferably 2 mm or more and 5 mm or less. Further, the clearance angle of the blade edge 22 in this case may be −1 ° or more and 0.5 ° or less, and more preferably 0 °, like the blade edge 21 described above. Also in this case, since the shape of the cutting edge in the rotation direction front side is a semicircular shape as described above, the ALC panel of fine cutting scraps scraped from the cut surface 41 of the ALC panel 4 that is the workpiece. 4 The upward jetting is suppressed. Therefore, the rotary blade cutting device 1 having the blade edge 22 can also exhibit the same effects as the rotary blade cutting device 1 having the blade edge 21.
＜軽量気泡コンクリートパネルの切削加工方法＞
本発明の軽量気泡コンクリートパネルの切削加工方法は、硬化後のＡＬＣパネルに切削加工により平滑面を形成するための部分切削又は面取り切削を、上述の回転刃切削装置１によって行う切削加工方法である。この切削加工方法は、図１に示すように、回転刃切削装置１を、回転胴３をＲ方向に高速で回転させながら、ＡＬＣパネル４に対してＤ方向に進行させながら行う。このように回転刃切削装置１を作動させることにより、ＡＬＣパネル４の被切削面４１を面状に削り取って、平滑な切削加工面４２を形成することができる。
<Cutting method of lightweight cellular concrete panel>
The lightweight cellular concrete panel cutting method according to the present invention is a cutting method in which partial cutting or chamfering for forming a smooth surface by cutting on the cured ALC panel is performed by the rotary blade cutting device 1 described above. . As shown in FIG. 1, this cutting method is performed while the rotary blade cutting apparatus 1 is advanced in the D direction with respect to the ALC panel 4 while rotating the rotary drum 3 at a high speed in the R direction. By operating the rotary blade cutting device 1 in this way, the cut surface 41 of the ALC panel 4 can be cut into a planar shape, and a smooth cut surface 42 can be formed.
例えば、ＡＬＣパネル４の表面を切削することによって、切削加工に伴ってＡＬＣパネル４の表面に露出する気泡の直径が２ｍｍ以上である場合には、最終的に当該気泡の露出している領域に塗装を施したとしても、アバタ状の凹みが塗装面に残りやすい。そこで目安として、直径２ｍｍ以上の気泡が切削加工面に露出している場合には、切削加工後に、当該気泡内に目止め剤を塗りこむ等の塗装前の下地処理が必須であった。しかしながら、本発明の軽量気泡コンクリートパネルの切削加工方法によれば、図３又は図４に示す通り、切削直後の段階において一時的に露出していた気泡４３の直径が２ｍｍ以上である場合においても、上述の通り、切削屑４４が、そのような気泡４３の内部に加圧されながら充填されていくことにより、切削加工面４２Ａは、少なくとも見かけ上は切削加工直後において十分に平滑な状態となり、上述のような下地処理を経ることなく、表面が平滑な切削加工面を形成することができる。 For example, by cutting the surface of the ALC panel 4 and the diameter of the bubbles exposed on the surface of the ALC panel 4 due to the cutting process is 2 mm or more, finally, in the region where the bubbles are exposed Even if painted, avatar-shaped dents are likely to remain on the painted surface. Therefore, as a guideline, when air bubbles having a diameter of 2 mm or more are exposed on the cut surface, a ground treatment before coating such as applying a sealing agent in the air bubbles after the cutting is essential. However, according to the lightweight cellular concrete panel cutting method of the present invention, as shown in FIG. 3 or 4, even when the diameter of the bubble 43 that was temporarily exposed immediately after the cutting is 2 mm or more, As described above, the cutting scraps 44 are filled in such bubbles 43 while being pressed, so that the cutting surface 42A is at least apparently smooth enough immediately after cutting, A cutting surface with a smooth surface can be formed without undergoing the ground treatment as described above.
尚、図１においては、回転刃２が、切削加工面４２の方向に抜けながら、回転刃切削装置１が進行していく所謂ダウンカットによる切削態様が図示されている。切削時にＡＬＣパネル４が不要に欠けて破損するリスクを低減するためには、このようなダウンカットによる切削が好ましい。但し、進行方向Ｄに対してＲとは反対方向に回転しながら切削を行う所謂アップカット方式の切削態様にも本発明の回転刃切削装置１を適用することができる。何れの切削態様においても、刃先の形状を本願独自の態様に最適化することによって、本発明の奏する上述の各効果を十分に享受することが可能である。 In FIG. 1, a cutting mode by so-called down-cutting in which the rotary blade cutting device 1 advances while the rotary blade 2 comes off in the direction of the cutting surface 42 is illustrated. In order to reduce the risk that the ALC panel 4 will be unnecessarily chipped and broken during cutting, cutting by such a downcut is preferable. However, the rotary blade cutting device 1 of the present invention can also be applied to a so-called up-cut type cutting mode in which cutting is performed while rotating in the direction opposite to R with respect to the traveling direction D. In any cutting mode, by optimizing the shape of the cutting edge to the mode unique to the present application, it is possible to sufficiently enjoy the above-described effects produced by the present invention.
図５は、本発明の回転刃切削装置を用いた切削加工方法によって形成された切削加工面と、従来の切削加工方法によって形成された切削加工面との、表面の平滑性の差異を記録した写真である。従来の一般的な回転刃切削装置としては、ダイアモンド性の刃先で、すくい角が０°逃げ角が１５°の装置（図２に示す形状の刃先を備える装置）を用いた。一方、本発明の回転刃切削装置として同材料の刃先で、すくい角が−３°逃げ角が−１°の装置（図３に示す形状の刃先を備える装置）を用いた。刃先の形状以外の切削装置のスペックや切削加工条件は全く同条件とした。具体的に、回転刃先端直径は２５０ｍｍ、回転数は３０００ｒｐｍ、切削加工対象としたＡＬＣパネルの搬送速度は、２２ｍ／ｍｉｎとした。４２Ａが本発明の回転刃切削装置によって切削加工した切削加工面である。本発明の回転刃切削装置により、従来の回転刃切削装置によって切削加工した切削加工面４２Ｂと比較して、著しく平滑性に優れる面が形成されていることが、明らかである。 FIG. 5 shows the difference in surface smoothness between the cutting surface formed by the cutting method using the rotary blade cutting apparatus of the present invention and the cutting surface formed by the conventional cutting method. It is a photograph. As a conventional general rotary blade cutting apparatus, a diamond-shaped cutting edge having a rake angle of 0 ° and a clearance angle of 15 ° (an apparatus having a cutting edge having the shape shown in FIG. 2) was used. On the other hand, as a rotary blade cutting device of the present invention, a device having a cutting edge of the same material and having a rake angle of −3 ° and a relief angle of −1 ° (device having a cutting edge having the shape shown in FIG. 3) was used. Except for the shape of the cutting edge, the specifications of the cutting device and the cutting conditions were exactly the same. Specifically, the tip diameter of the rotary blade was 250 mm, the rotation speed was 3000 rpm, and the conveying speed of the ALC panel targeted for cutting was 22 m / min. 42A is a cutting surface cut by the rotary blade cutting device of the present invention. It is apparent that the surface of the rotary blade cutting device of the present invention is remarkably excellent in smoothness as compared with the cut surface 42B cut by the conventional rotary blade cutting device.
